About One-stop for Geoscience Knowledge Graph (GeoOpenKG)
Why Geoscience Knowledge Graph
Geoscience knowledge graph (GeoKG) is a computer-understandable, computable, and deducible semantic web that effectively organizes and represents geoscience knowledge and its mutual relations. GeoKG is the cornerstone of geoscience big data integration and mining analysis, geoscience knowledge computational reasoning and discovery, and geoscience artificial intelligence. In the Deep-Time Digital Earth (DDE) Program, GeoKG and geoscience big data constitute the core scientific resources of DDE, support the research of major scientific issues driving the evolution of the earth, and lay a solid foundation for promoting the transformation of the paradigm of geo-scientific research.
Why One-stop for Geoscience Knowledge Graph
The geoscience knowledge is implied in the data of different modes such as scientific papers, monographs, standard specifications, and network texts, as well as in the minds of geoscientific experts in the field. The knowledge of various disciplines also has different forms and types. Therefore, different countries and related international organizations around the world have carried out a large amount of research work related to GeoKG, and established a series of related geoscience concept terminology, knowledge ontology and knowledge base. However, up to now, there has not been a systematic, standardized and consistent global GeoKG that can cover all disciplines of solid earth science. To achieve this goal, DDE initiated the GeoKG constructive task, aiming to build and share the global GeoKG through the joint efforts of global geoscientists.
Functions, Services in GeoOpenKG
Currently, knowledge covering 22 disciplines is provided on the GeoOpenKG website, including 106.3k geo-knowledge nodes, 58.4k geo-knowledge relations, 6911.2k geo-knowledge triples, 25 website directory navigations related to geo-knowledge base, and there are 307 knowledge contributors.
In OS4GeoKG, geoscience researchers and other global users can access, share or invoke the Basic Ontology for Geoscience Knowledge Graph (BO4GK), multimodal Geoscience Academic Knowledge Graph from literature (GPKG) and Geoscience Professional Knowledge Graph created cooperatively by Experts (GPKG) that are all established by DDE, and other online open geo-knowledge terms, ontologies and Geoscience Knowledge Graph Open Directory (GKGD) in one stop. Users can also collaborate to create new geo-knowledge (concepts, attributes, relations and rules, etc.) or evaluate the existing geo-knowledge of DDE to continuously improve and complete DDE Knowledge.
